Two Marley cooling towers and a York centrifugal chiller was used to cool a
100,000 square foot office building. Chemical costs were $4,500 annually to
maintain the system and keep it free of scale and algae. The facility manager
cleaned the chiller and tower annually using two men for a two day period.

Solution:

The Electronic Descaling 2000 units were installed on
the 6" water inlet, the 6" water outlet and the 2" makeup line
near the chiller.

The facility manager eliminated the annual expense of the scale inhibiting
chemicals.

The system continues to operate without any degradation of thermal
performance.

The annual cleaning of the condenser tubes and the tower has been reduced
to a light washing.
